The Joker is more than wild. It's a tribute to the power of Heath Ledger's transcendent performance in The Dark Knight (* * * * out of four) that we can watch him, transfixed and deeply unsettled by the character's creepiness, laugh at his comic menace, and still manage to block out thoughts of the actor's tragic and untimely death. This is a career-making performance if ever there was one. Too bad it was a career-ending one as well.
